BPS access protection

Function sheet

The spectrum of possible operating functions at the automation level is complex

and requires different access rights. The VISONIK BPS thus has three access

levels which can each be protected with an individual password.

The following illustration uses typical examples to show the use of operating levels and

access rights on the VISONIK BPS with PC operation.

The three operating levels and their access rights listed below are referenced to the

above illustration. The lower level immediately following includes the functions of the

higher level.

Access rights

1 Starting alarm and system reports. Reading process variables such as:

Room temperature, outside air temperature, etc.

2 Reading and writing setting parameters such as: Heating curves (HC),

time switch program (TSP), etc.

3 Access to all process parameters and setting variables such as those

for the controller block (RGB).

Access to the programs in the VISONIK BPS.

It is possible to set up PC operation with COLBAS (VISOTOOL Editor) for all three

levels: menu-guided PC operation (operator program) is possible for levels 1 and 2. In

both cases, the functionality depends on the password entered and the operating level

associated with it.
